Live Meeting Remote Access Problems

Hi,

I'm having a problem accessing Live Meeting from outside of the network.

I have OCS 2007 with an edge server. The edge server has public IP addresses and can communicate with the internal OCS 2007 server. I have enabled remote access on the Edge server and on the users, also I've enabled anonymous access.

The error I'm getting is: Live Meeting cannot connect to the meeting. Wait a few moments, and then try to join the meeting again. If you still cannot connect, contact your administrator or technical support.

The only 2 errors I can see in the logs are Event ID 42000 on the edge server and Event ID 14507 on the OCS 2007 server:


********************************************************************************************************
Event ID 14507

Failed to find Web Conferencing Server specified by client

Over the past 0 minutes Office Communications Server has disconnected client(s) 1 times because it could not find connections to <LOCAL OCS SERVER> The last such disconnected client is 58.171.147.105:2102
Cause: Client connection was disconnected because the Web Conferencing Server specified by client was not found
Resolution:
Check to make sure there are valid connections from Web Conferencing Server specified by client

Event ID 14507

At least one attempt to reference stale (non-existent or deleted) security association was detected.

There were 1 messages with signature that referenced stale (non-existent or deleted) security association in the last 0 minutes. The last one was this SIP message:

Cause: This could be due to users that utilize large number of devices (in excess of configured maximum), or due to connection refresh logic re-balancing remote users to a different director in a bank or a pool, or it could be due to an attacker.
Resolution:
None needed unless the failure count is high (>100). Check if number of allowed devices per user is too low for existing usage scenarios. Check your network for any rogue clients. Restart the server if problem persists.

I can connect to Live Meeting from inside the network or over VPN.
I can connect to IM/Presence, Federation, Audio/Video calls externally and internally
I can telnet to 443 (the live meeting port) on the live meeting IP.
When I do a test of the connection from the Live Meeting Options it says the connection it OK.
All SSL certificates report OK

Any ideas?

Thanks,

Ben
